CAR-COUPLING.

SPECIFICATION forming partv of Letters Patent No. 243,486, dated June 28, 1881.

Y Application filed May 4,1881. (No model.)

To all whom it may concern Be it known that I, NICHOLAS BARR, of Oayuta, in the county of Schuyler and State of New York, have invented a new and useful Improvement in Car-Couplings; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a vertical longitudinal section of my improved car-coupling'. Fig. 2 is 'a plan view, and Fig. 3 a front view, ofthe same.

My invention relates to improvements in ear-couplings; and it consists in the peculiar construction and arrangement of the parts,

' whereby' all danger ofaccident in coupling and I uncouplin g ears is avoided, as hereinafter more fully set forth.

In the accompanying drawings, a represents a draw-head, provided with a slot, b, in its lower face, and an inclined plane, c, in the opening in the draw-head in rear of the end of the slot. The slot b is intended for the reception of the rear end of the coupling-bar c, provided with a hook at each end, the rear hook, d, being inserted in the slot b in the lower face of the draw-head, and then turned so that the lower face of the hook rests on the inclined plane e. By this construction the coupling-bar is pivoted to the draw-head without the use of the usual pivot-bolt, and can readily be removed or inserted.

The coupling-bar is provided wit-h a rear hook, d, and a hook, f, at its forward end, adapted to engage with a lilik of the usual construction, the coupling-bar lying beneath the draw-head. Y

g represents a bent dat spring, the lower part of which rests in a recess inthe lower face of the opening in the draw-head, the bent upper portion of the spring, in its normal position, lying in a recess in the upper face ot`the opening in the draw-head.

h represents a rod bent so as to conform to the shape of the draw-head, its upper end passing through a hole in the upper face of the drawhead,immediately over the end ofthe spring g, the opposite lower end of the rod h having secured to it a cord or chain, i, passing around a pulley, j, in the frame 7c, bolted to the lower face of the draw-head, and provided with a spring, m, lying under the hooked coupling-bar c. By this construction the chain i can be operated or pulled without the operator coming between the ears, the rod brought downward to bear against the outer end ofthe spring g, which presses against the inner end of the link Z, thus raising the outer end of the lilik to the desired elevated position for coupling two cars.

To the outer end of the coupling-bar c, beneath its hook, is secured a chain or cord, n, which passes thence around the pulleyjin au opposite direction to that of the cord or chain t', whereby the coupling-hook Vcan be pulled out of engagement with the link and the cars uncoupled. The link, when two cars are to be coupled, strikes the hooked end of the coupling-bar, depresses it, and allows the link to enter the opening in the draw-head, when the spring below the coupling-hook raises the latter into engagement with the link.

What I claim as my invention is- 1. The combination, with the draw-head a, provided with the slot b, and inclined plane c in rear of said slot, of the coupling-bar c, having hooks df, substantially as described, and for the purpose set forth.

2. The combination, with the draw-head a and spring g, of the rod h, chain fe', frame 7c, having pulley j, link l, and coupling-hook c, substantially as described, and forthe purpose set forth.A

3. Thecombination ofthe draw-head @,spring g, rod h, chain z', frame 7c, pulley j, spring m, link Z, and coupling-hook c, having chain n, substantially as described, and for the purpose set forth.

The above specification of my invention signed by me this 20th day of April,'188l.

NICHOLAS BARR.
